GRE Tunnels

GRE encapsulates IP packets to enable data transmission through an IP tunnel. The resulting encapsulated packet contains a GRE header and a delivery header. Consequently, the packet requires more processing than an IP packet, and GRE can be slower than native routing protocols.

GRE tunnels can be secured with IPSec. See Securing L2TP and IP Tunnels with IPSec .
